“…The T max , a proxy for thermal maturity, was determined from the temperature at which the S 2 peak reaches maximum generation. Thermal maturity values determined from T max values within the dataset are consistent with reported conodont color alteration indices (CAI) of 2 to 2.5 for the region of the Marl Hill borehole (Metcalfe and Riley 2010). The CO 2 generated during the thermal breakdown of kerogen was recorded as the S 3 peak of the pyrogram.…”

“…The Bowland Shale is similar to the Barnett Shale play of the Fort Worth Basin (USA) with both being mid-Carboniferous calcareous organic-rich shales (Andrews 2013;Hough et al 2014), although critically it differs with respect to its thickness (over 500 m or 1600 ft in some localities), its paleogeography (accumulation in a series of smaller basins) and its geological history (complex including phases of basin inversion). In addition, the hydrocarbon potential of the Bow-land Shale differs from the Barnett Shale of the Fort Worth Basin as significant areas within the Pennine Province do not have sufficient thermal maturity for the organic matter of the Bowland Shale (and its lateral equivalents) to generate gas (Jarvie et al 2007;Metcalfe and Riley 2010).…”

Can One-Run-Fixed-Arrhenius Kerogen Analysis Provide Comparable Organofacies Results to Detailed Palynological Analysis? A Case Study from a Prospective Mississippian Source Rock Reservoir (Bowland Shale, UK)

Organofacies analysis, a fundamental component within source rock appraisal based on the study of kerogen within a source rock, is typically produced from microscopy (palynological) and geochemical (kerogen kinetic) data, both of which are costly to acquire. One-Run-Fixed-Arrhenius (ORFA) kerogen kinetic analysis based on Rock-Eval pyrolysis offers a substantially cheaper kinetic dataset. Here, ORFA and palynological analyses are compared in organofacies characterization of a prospective Mississippian source rock reservoir (Bowland Shale, UK). Two-end-member organofacies were determined based on the abundance of the 56 kcal/mol activation energy peak derived from ORFA data: absence (< 5%) indicating Ôorganofacies AÕ containing the highest proportion of algal material (Type I kerogen); and presence (> 15%) indicating Ôorganofacies BÕ containing the highest proportion of sporomorphs (Type II kerogen). A mud-dominated slope setting for the rock reservoir was also used to test the accuracy of organofacies analysis in determining depositional environment. Organofacies A found within lithofacies deposited from dilute waning density flows and hemipelagic suspension settling occurred between shelf edge, slope and basin. Organofacies B found within lithofacies deposited from dilute waning density flows, and low-strength cohesive debrites occurred only within the lower slope. This study demonstrates that ORFA kerogen kinetic analysis provides comparable net results to palynological analysis, enabling cheaper and faster organic characterization during initial source rock appraisal. However, caution must be exercised in drawing interpretations as to biological source(s), organic matter mixing and preservation state(s) without additional investigation using data from detailed palynological analysis.

“…In Ukraine and Craven Basin in England, the first occurrence of L. ziegleri is also certainly late, that is, at levels close to the base of the Namurian (maybe equivalent to the uppermost Tarusian to lowermost Steshevian; Fig. 6) (Metcalfe, 1981;Skompski et al 1995;Sevastopulo & Barham, 2014). However, some authors inferred its FOD within B8-B9 limestones or sequence Se-I of the Donets (Davydov et al 2010;Eros et al 2012), although the oldest confirmed FOD of this taxon in Ukraine is in sequence Se-VII, which probably corresponds to the Steshevian Substage (Cózar et al 2019).…”

Foraminifers and conodonts in the Danlu section, South China: implications for the Viséan–Serpukhovian boundary (Mississippian)

et al. 2023

The Viséan–Serpukhovian boundary is poorly defined in South China, hampering regional and global stratigraphical correlations. The foraminiferal and conodont distribution of the Baping Formation in the carbonate-slope Danlu section permits the recognition of an interval from the middle Viséan to the uppermost Serpukhovian in a continuous succession. The base of the Serpukhovian in Danlu is recognized by the first occurrences of Janischewskina delicata, Howchinia subplana and questionable ‘Millerella’ tortula. At a slightly younger level, the conodont Lochriea ziegleri is first recorded. A calibration on the first occurrence of L. ziegleri in different basins at a global scale has been revised compared to auxiliary markers within the ammonoids and foraminifers. The late occurrence of L. ziegleri in the Danlu section also supports a lack of synchronicity in the global first occurrence of this taxon. This study calls for the recognition of a new base for the Serpukhovian under a far better correlation between different zonal schemes and fossil groups.
